Does anyone know what type of bird's nest this because I only see the Robin, but they're not blue??!!

 So the only bird I've seen hopping in and out of this planter is a Robin, but I've since been told that Robins eggs are blue. Dos anyone recognise these eggs please? We mainly get robins, blue and coal tits, sparrows, wrens, blackbirds and chaffinches in our garden.

I also accidentally disturbed the plants covering it as was doing my gardening and tidying up, does this scare the mum away? thank you
